Additional granulated sugar (Note: the recipe in this book used confectioner's sugar, but according to our Finnish relatives, granulated sugar is the authentic way to make them. I think they are superior with the granulated sugar)
Instructions
Brown the butter by melting it in a medium saucepan over medium heat. Stir occasionally. When butter begins to foam up, stir constantly until it turns a deep golden brown. Watch carefully, because at this point, the color changes quickly. It takes about 7 minutes to brown. Cool to room temperature.
Heat oven to 325 degrees. Mix the flour and baking soda together.
Combine the cooled butter, sugar, and vanilla in a medium bowl and stir until evenly mixed. Add the flour and mix to form a dough.
Shape the cookies by placing about 1 teaspoon of dough into the bowl of a teaspoon (a real teaspoon, not a measuring teaspoon) and pressing against the side of the bowl, leveling the top. Press out cookie, flat side down, onto an ungreased baking sheet.
Bake 10-13 minutes or until lightly browned and set. Let cool on baking sheet for 2 minutes and remove to wire cooling rack.
While cookies are still warm, roll in additional granulated sugar, shaking off excess.* Let cool completely.
When cooled, spread a scant ½ teaspoon of jam on the flat side of one cookie. Make a sandwich by pressing the flat side of a second cookie onto the jam. Makes 24 sandwich cookies,
*If you wish to dust with confectioner's sugar instead, let cookies cool without rolling in sugar. After cooling and filling with jam, then dust the tops with confectioner's sugar.
